Generic 6AN 70" Transmission Cooler Hose Line Kit for GM & Ford — Stainless-Braided PTFE, AN6 Fittings

High-pressure 6AN stainless braided PTFE transmission hose kit engineered to route fluid between your transmission and cooler for improved heat management on a wide range of GM and Ford vehicles.

This complete 70" line assembly uses stainless-steel-braided PTFE hose and AN6 fittings to replace factory soft lines or add an auxiliary cooler. It is built for compatibility with many automatic and manual transmissions—including 4L60E, 4L80E, TH350/TH400, 700R4, TR6060 and multiple Ford AOD-series units—so you can upgrade plumbing for towing, heavy loads, or restoration projects. The kit emphasizes corrosion resistance, high burst strength and flexible routing in tight engine bays.

Which transmissions and vehicles does this hose kit fit?

The kit was designed for wide compatibility across GM and Ford families and specific models using common transmission fittings. It fits popular GM transmissions (4L60E, 4L80E, TH350/TH400, 700R4, 200-4R, TR6060, C5) and Ford units (AOD, 4R70W, 4R100) with AN6 adapter requirements. Check fitment notes for model-year specifics before ordering.

• GM coverage: Chevy Silverado, Tahoe, Suburban, Corvette, Camaro, Yukon, Avalanche, Colorado/Canyon and many Holden/Buick/Cadillac platforms.
• Ford coverage: F-Series, E-Series, Bronco, Mustang and related Lincoln/Mercury models listed by year ranges.
• Specialty: TR6060 fitment for performance Mustangs, Corvettes and Camaros; 4L80E for heavy-duty GM trucks and select luxury/European cars.
• Confirm using your transmission type and year-range before installation.

How does stainless PTFE braided hose help transmission cooling?

PTFE hose with stainless braid resists heat, abrasion and pressure better than rubber lines, giving a more durable path for fluid to and from a cooler. That improves cooling efficiency and reduces the risk of leaks when towing, hauling or track driving. The robust construction also simplifies routing around hot exhausts and sharp edges.

• PTFE core for chemical compatibility with ATF and smooth internal flow.
• Stainless braid for abrasion resistance and higher burst strength.
• AN6 fittings provide a secure, reusable connection to aftermarket coolers and adapters.
• 70" length offers flexibility for custom routing in trucks and SUVs.

What should I expect during installation and maintenance?

Installation typically requires replacing the factory feed/return lines or adding an adapter to the transmission cooler ports. The kit is made for bolt-on fittings but may need clamps or flare adapters depending on your vehicle. Routine checks for tight fittings and chafe protection keep the system reliable.

• Inspect original transmission ports and select the correct adapter for your model.
• Route away from sharp edges and exhaust heat; use protective sleeving or clamps where needed.
• Bleed air from the system after filling; verify no leaks at startup and under load.
• Periodically re-check fittings and braid integrity during service intervals.

What materials and performance characteristics are included?

The hose combines a PTFE inner liner with a stainless-steel braided outer layer for long service life and stable performance under pressure. The assembly is built to resist corrosion, maintain flexible routing characteristics and minimize leak potential at connection points. This makes it suitable for everyday driving, towing or performance use where elevated transmission temperatures are a concern.

• PTFE liner: chemical compatibility and low friction for consistent flow.
• Stainless braid: corrosion resistance and mechanical protection.
• AN6 fittings: durable, reusable connections compatible with many coolers.
• Designed to improve cooling capacity when paired with an appropriately sized cooler.

Who is this for: This hose kit is aimed at DIY mechanics, restoration shops and performance enthusiasts who need a durable, universal AN6 transmission line for GM and Ford drivetrains. It's suitable when replacing failing rubber lines, adding an auxiliary cooler for towing, or upgrading plumbing for high-performance/HV cooling needs. Confirm your transmission model and port type to ensure a correct fit before purchase.
